<p>The class defines a C++ STL-styled vector (a variable-sized array) optimized for the case when the array is small. It contains some number of elements in-place, which allows it to avoid heap allocation when the actual number of elements is below that threshold. This allows normal <em>small</em> cases to be fast without losing generality for large inputs. All the methods in <a href="https://en.cppreference.com/w/cpp/container/vector">std::<wbr />vector</a> can apply to this class.</p><p>The class is stripped from the LLVM codebase.</p>
